It looks like the real import path to the project is go.uber.org/zap
instead of github.com/uber-go/zap since the example in the project
references that path.
This was needed when we were on go 1.4 but hasn't been needed since go
1.5. It was kept because we weren't sure if we were going to have to
rollback to an older version of Go at that time and we kept it so we
wouldn't forget to readd it.
Now that we are on go 1.7 with go 1.4 deprecated, there is no going back
so we might as well remove this so people can set GOMAXPROCS to a custom
value using environment variables.
The logging library has been switched to use uber-go/zap. While the
logging has been changed to use structured logging, this commit does not
change any of the logging statements to take advantage of the new
structured log or new log levels. Those changes will come in future
commits.
`percentile()` is supposed to be a selector and return the time of the
point, but that only got changed when the input was a float. Updating
the integer processor to also return the time of the point rather than
the beginning of the interval.
NO-OP on platforms with unix path separator.
On Windows paths get converted to slashes before adding to archive and back to backslashes during restore.
The `partial` tag has been added to the JSON response of a series and
the result so that a client knows when more of the series or result will
be sent in a future JSON chunk.
This helps interactive clients who don't want to wait for all of the
data to know if it is done processing the current series or the current
result. Previously, the client had to guess if the next chunk would
refer to the same result or a new result and it had to match the name
and tags of the two series to know if they were the same series. Now,
the client just needs to check the `partial` field included with the
response to know if it should expect more.
Fixed `max-row-limit` so it counts rows instead of results and it
truncates the response when the `max-row-limit` is reached.
There are 2 new keys in the configuration file.
- security-level: "none", "sign", or "encrypt".
- auth-file: The location of the user/password file.
Please see the collectd network doc for more details.
When a query would use a grouping with two different aggregates, it was
possible for one of the aggregates to return a value from a different
series key than the second aggregate. When these series keys didn't
match, the returned grouping would be screwed up because it sorted by
time before checking for name and tags.
This did not happen when the aggregates returned values for the same
series keys because then the iterators were aligned with each other.
When a limit is exceeded, we return errors and sometimes log (if appropriate)
that a limit was exceeded. The messages don't always provide an indication
as to where or how they are configured.
Instead, return the config option (easily searchable for) as well as the limit
currently set and the value that exceeded it when possible.
The admin console would dynamically discover the version from the
InfluxDB server, but for patch releases, it included the patch in the
link to the documentation and that wasn't a valid link.
Truncate the version so the documentation url is correct since we only
do documentation for `major.minor`.
Changes the default time boundaries for raw queries so raw queries will
range until the end of time. Aggregate queries continue to have their
default end time be `now()`.
The information in the usage string for the `help` command about
how to get more information about a specific command was incorrect:
"influxd help [command]" does not work, but "influxd [command] --help"
does.
The `cumulative_sum()` function can be used to sum each new point and
output the current total. For the following points:
cpu value=2 0
cpu value=4 10
cpu value=6 20
This would output the following points:
> SELECT cumulative_sum(value) FROM cpu
time value
---- -----
0 2
10 6
20 12
As can be seen, each new point adds to the sum of the previous point and
outputs the value with the same timestamp.
The function can also be used with an aggregate like `derivative()`.
> SELECT cumulative_sum(mean(value) FROM cpu WHERE time >= now() - 10m GROUP BY time(1m)
The tags passed into Statistics() calls are not supposed to be modified.
The balanceWriter in subscribers tried to modify them triggering a panic
because they can be nil.
It is now possible to use a mixed duration unit like `1h30m`. The
duration units can be in whatever order as long as they are connected to
each other.
There is a change to the scanner. A token such as `10x` will be scanned
as a duration literal, but will then fail to parse as an invalid
duration. This should not be a breaking change as there is no situation
where `10m10` was a valid order of tokens for the parser.
Fixes#3634.
Instead of having the parser set the defaults, the command will set the
defaults so that the constants for that are actually used. This way we
can also identify which things the user provided and which ones we are
filling with default values.
This allows the meta client to be able to make smarter decisions when
determining if the user requested a conflict or if the requested
capabilities match with what is currently available. If you just say
`CREATE DATABASE WITH NAME myrp`, the user doesn't really care what the
duration of the retention policy is and just wants to use the default.
Now, we can use that information to determine if an existing retention
policy would conflict with what the user requested rather than returning
an error if a default value ever gets changed since the meta client
command can communicate intent more easily.
This commit fixes the `MaxSelectSeriesN` limit which was broken by
the implementation of lazy iterators. The setting previously limited
the total number of series but the new implementation limits the
concurrent number of series being processed.
Updating the help formatting for all of the commands for consistency.
Removed tabs from the output in favor of using spaces so it is more
clear how the output is intended to look.
Truncate the time interval output of the monitor service to be on even
time intervals rather than on every minute based on the start time. This
normalizes the output from the monitor service.
